f A, Tp all 'whom it may concern it known-,that Tous R. MrreHELL,

flllinois have invented ,al newand useful Improvement in Draft-Riggingfor Railwayv(lars, of which the`following is a specificainventiorlrelates to improvements in draft rigging for railway cars.

I -Icretofore the draft sills or timbers to vwhich the draft lugs orstops plates of the draft rigging are directly applied have ordinarilybeensecured to the center sills of the car by vertical bolts passingI upthrough the draft timbers and center sills, and considcrable annoyance,delay and difficulty is fr ",practically experienced in cases where itis necessary, by reason of wreck or other cause,

Arcxnmeand replace a dratt timber, as

j :these bolts cannot be removed without un.i

-ioiuiing the ca r when loaded with such l freight as lumber orgrain orthe like.

with great rigidity.

My invention consists in the means l employ to practically accomplishthis object or result herein shown and described and more particularlyspecied in the claims.

Inthe accompanying drawing forming a part of this specification, Figurel 1s a side elevation partly in vertical longitudinal section of a draftrigging embodying my invention. Fig. 2 is aplan view.` Fig. 3 1s apartial` cross section on line 3---3 of Fig. 2.

Fig. 6is a\detail perspective view of the 'combined draft rigging, guide andbottom plate. Fig. 7 is a detail perspective view showing a modificationin which the draft rigging bottom guides and bottom plates are madeintegral with each other so as to serve also as a. tie-plate. Fig. 8 isa detail cross section illustrating a modification in which the anchorbrackets on both sides of the center sill are made integral with eachother, or of a saddle form fitting astride the center sill.

Aand 12 are cross sectional 4views'showing slightly modifiedconstruetions.

In the drawing, A A represent the center I sills of a railway car, Althe end sill, A2 the buffer block, Asthecarry-iron, B the drawf bar, B1the drawbaryoke, C, c, 01, c? springs or cushioning devices of the draftrigging, D the 'followers and E the draft lugs or stop members of thedraft rigging which are secured to the draft sills ortimbers F.' Allthese parts are or may be ofany suitable construction lmown to those'skilled in the art. i l' The draft sills or timbers F'whieh. lit underthe center sills A, instead of being secured thereto by bolts passing upthrough the draft timbers and center sills, I removably' secure 'tothecenter .sills by anchor brackets Gr, 'H, zfittingon each side ofthecenter sills and connecting boltsK and bottemplates M which fit belowthe draft timbers F and through' whichv the connecting bolts K extend.

The anchor brackets-Gfit on the 'inside bf' the' center sills A. abovethe draft lug or stop plates E, 'and' are each securely fixed vto thecenter sills by horizontal bolts g which eX.- tend through these anchor'brackets and the center sills.' 'l`hean chor brackets G have projectionsg1 fitting iii suitable'gai-ns a' in the inner upright tage of thecenter sills to aid in securing them firmly and rigidly to the centersills. The anchor" brackets G are further provided with aprojeetingshoulder g2 having slots g3 and kbracewebs g4 and shoulders y?to receive the head connecting boltl K.

The anchor brackets H which 'fit on the outside of the center sills Afndon the inside of the center sills et the rear of the draft lug or stopmembers E are in the nature of double brackets of the same generaldescribed. These double anchor brackets H K1 ofthe fit against theupright faces of both the cenf ter sill A and draft timber F, thusbridging the two and tile projection k on the inner.

anchor bracket H is furnished with a nori i cu te upon.

In the modification illustrated in Fig. 7, thil oinbincd bottom plate:ind guide on each side of the draft rigging :ire formed in oneintegral. piece M, thus serving also es :i tieplzite.

ln the nioditied construction slwwn in Vic'. 11, the anchor brackets Gare furnished on tlsei r inner feces with lugs or projections y" which.tit in corresponding gains or iotches in the center sill A to nid inholding tin position on the center sill.
